I don`t know about ibooks, but I replaced the CMOS battery on my powerbook G4 myself. The problem when these die is that the computer does not know on what power to run: battery or outlet. If your CMOS battery is dead and and your Li-ion battery is dead, the computer will not be able to start on the outlet. The temporary fix: recharge the Li-ion battery on another mac. Apple says it costs too much to replace, because I am pretty sure they designed it it that way so that people have to buy a new laptop when their CMOS battery dies. I`d stil open the laptop and see how easy it is to replace. It was free, after all...
